Hello Julien,
Thanks for your response.
I'm in touch with our hosting team to get more information for your queries.
As of now I can share these details.
We did analyze on the DB, but not the vacuum,
We are using AWS RDS.
Please help me with these queries as well.
1) Will the process change if we use AWS RDS.
2) What kind of vacuum should be done on the DB, as there are many types of vacuum.
Awaiting your reply!
Thanks!
Regards

First of all, this is not a bug. You should have instead started a discussion
on pgsql-general or pgsql-performance. I'm redirecting the discussion on
-performance.

How did you upgrade?

Do you have any errors in the postgres logs?

It depends on how you did the upgrade. If you used pg_upgrade, did you run the
generated script as documented in step 13 at
https://www.postgresql.org/docs/current/pgupgrade.html?
Otherwise, at least a database-wide VACUUM ANALYZE on every database is the
bare minimum to run after an upgrade.
